Abstract
The present invention relates to a lighting fixture that functionally provides a mold for creating a light diffuser from ice, a stand upon which to display the created light diffuser (including a shaped-surface support element to stabilize the light diffuser as it de-solidifies), a collection element to collect and contain the melted light diffuser material, and a support and containing system for a light source that, in use, is surrounded by the light diffuser.

9. The lighting fixture of claim 8 , said collection element further comprising an interior base having a gradual concave curve extending radially from said near-vertical column toward said outer wall.
10. The lighting fixture of claim 9 , wherein a lowest point of said radially-extending gradual concave curve of said interior base is radially positioned based upon radially varying rates at which portions of said light diffuser de-solidify.
11.

12. A lighting fixture as set forth in claim 1 , wherein said light source is a candle.
13. A lighting fixture as set forth in claim 12 , wherein said candle is contained in a light source centering holder.
14. A lighting fixture comprising:
a light source;
a light diffuser substantially surrounding said light source, said light diffuser constructed of a diffuser material initially in solid form but which de-solidifies at room temperatures; and
a base structure to support at least said light diffuser, said base structure including a core member having a substantially horizontal surface element to support said light diffuser, wherein said substantially horizontal surface element has at least one drain hole through which a melted portion of said light diffuser can pass.
15. The lighting fixture of claim 14 , the core member comprising a centrally located shallow hollow vertical column to support and contain said light source.
16. The lighting fixture of claim 15 , said shallow hollow vertical column having formed therein one or more openings through which air can flow.
17. The lighting fixture of claim 16 , wherein said opening is a scallop opening comprising a circumferentially intermittent supporting perimeter along a base of said shallow hollow vertical column suitable for supporting a light source centering holder, said light source centering holder being of such size and shape that said light source centering holder cannot pass through said scallop opening.
18. The lighting fixture of claim 17 , wherein said light source centering holder is shaped such that said light source centering holder is incapable of totally blocking said scallop opening and preventing air from passing through portions of said scallop opening.
19. The lighting fixture of claim 14 , wherein said substantially horizontal surface of said core member comprises at least one low-profile vertical wedge.
20. A lighting fixture as set forth in claim 14 , wherein said light source is a candle.
21. A lighting fixture as set forth in claim 20 , wherein said candle is contained in a light source centering holder.
22. A lighting fixture comprising:
a light source;
a light diffuser substantially surrounding said light source, said light diffuser constructed of a diffuser material initially in solid form but which de-solidifies at room temperatures; and
a base structure to support said light source and said light diffuser, said base structure comprising a core member having an inner circumference, an outer perimeter circumference, and a substantially horizontal surface having a gradual concave curve extending radially from the inner circumference surrounding said light source toward the outer perimeter circumference of said core member.
23. The lighting fixture of claim 22 , wherein a lowest point of said radially-extending gradual concave curve is radially positioned based upon radially varying rates at which portions of said light diffuser de-solidify.
24. The lighting fixture of claim 23 , wherein the lowest point in said radially-extending gradual concave curve is circumferentially located approximately two-thirds of a radial distance from said inner circumference surrounding said light source to an outermost point of said radially-extending gradual concave curve.
25. The lighting fixture of claim 22 , wherein said substantially horizontal surface further comprises a ribbing pattern with a plurality of alternating ridges and valleys that each extend radially outward from said inner circumference.
26. The lighting fixture of claim 25 , wherein each said valley further comprising a drain hole through which a melted portion of said light diffuser can pass.
27. The lighting fixture of claim 26 , wherein each said ridge further comprises a plurality of shallow flow guides running from a crest of said ridge to said drain hole.
